Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
prioritize the substances of highest concern for human health. In this context, genotoxicity is a key (toxicological) endpoint as it is related to a broad range of adverse human health effects including ...
A new approach to define acceptance limits for hematology in external quality assessment schemes.
each target concentration range. For deriving AL, focus was mainly on the upper percentiles (90th, 95th and 99th). RESULTS: For RBC, hemoglobin, hematocrit and MCV, no relation was found between the ...
